I did search and read here but I can't find the exact info I need. Some of you here may know I replaced my water pump last weekend. I had some parts problems and had to take it all apart and install a new pump from a different parts store. Everything is all put back together now, and I believe I have solved a couple of leak problems it had.
My truck has a 14.5 quart cooling system capacity. When I started on the job the first time I drained the system by remvoing the lower rad hose. I can't find any drain on the rad itself. I don't know how much coolant drained out that way. Then more coolant drained out when I took the water pump off the front of the engine. I don't know exactly how much it was. Then when I put it all back together the first time I added a gallon of plain green coolant from Autozone. Then I added about half a gallon of distilled water. I put some 50/50 premixed coolant I already had in the overflow tank. Engine ran OK but I had leak problems with the new water pump.
I put on a new water pump on Monday. I put in another gallon of green Autozone coolant and about half a gallon of the coolant/water mix that I drained out when I took the water pump off for the second time. The coolant was new so I drained it into a clean drain pan so I could re-use it. I added a small amount of distilled water over the next 2 days to bring the level up to the bottom of the fill neck.
I need to know what is this ratio of water to coolant? I think there might be too much coolant and not enough water now. My truck runs OK now but seems to be sort of holding back a little. I filled up the gas tank today and am off by about 1 MPG too. I would guess when removing the water pump and the lower rad hose it drained about 2 gallons out of the system. I have no way to know for sure because on both times when I removed the lower hose and the pump, a lot of what came out splashed on the garage floor. It was a huge mess.
Sorry for such a long post but I wonder if my coolant to water ratio is correct. Service Manual calls for 50/50, I think it's more like 70/30 now, maybe even more than that and I am worried it will cause problems with my engine both internally and in performance/MPG. The truck ran better before I replaced the water pump. Plus it had more condensation out the tail pipe and for a longer period of time after a cold start in the morning.
Is there a way to test the ratio and be sure or should I just dump it all again and do it over one more time? There's a good honest garage down the street, I am seriously thinking about having them just do a BG power flush on the coolant. Then I should know for sure that I have the right coolant/water ratio.
Thanks for any help or ideas. I just want to be sure I have this done correctly.
